[SIZE=medium]Unstable strains are strains that have not been fully crossed and are unstable. Example: I cross a Brainstrain with a Morich the 1st year it is a F1 and not stable. I then have to keep breeding those 2-4 back and forth every year until I get all the pods with the same characteristics. If you have a greenhouse and can grow all year then the time is shortened maybe 5 years or 10 crosses. Most take 10 years. As far as BREEDING anything goes (plant wise) these days ,it takes several seasons in isolation (8 minimum) to see what you have as far as stability goes. 8 seasons is IF it grew stable and needed no back crossing etc. Breeding takes a LOT of work but it’s fun to play with.[/SIZE]
